Application filed April 9, 1900, s rial No, 12,106, (3pccimens.)

T0 aZZ whmn it may concern:

Be it known that I, WALLACE WILSON, a citizen of the United States, residing at No. 2827 Penn street, Frankford, in the city of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Processes of Making Bicolored Hosiery,of which the following is a specification.

Heretofore hosiery and knit goods when two or more colors have been desired have been knit with colored yarn or thread. My invention relates to a process whereby I am able to knit hosiery with undyed yarn or thread and subsequently produce the necessary color contrast by dyeing in the piece. More particularly, it relates to a process of making a stockingin which the foot and leg of the stocking are made of wool and dyed such ground color as may be desired, while the tip of the heel and toe are made of mercerized cotton and dyed a contrasting color and resembling silk.

Heretofore the only method of producing hosiery having the tip of the heel and toe contrasting with the ground color has been todye the yarn or cotton or silk in the skein and knit with the colored yarn, throwing in the contrasting threads at the proper point of the knitting pperation. There are many disadvantages incident to this method. The skeining of the yarn is itself expensive. Dyed yarn does not knit as easily as undyed yarn and is liable to break. Undyed yarn can be knit under a higher tension, creating a closer knitting. Transfer-Workis very difficult with dyed knitting,especiallyif the colors are dark, and can be done by the ordinary operative much more accurately and rapidly with white yarn than with colored knitting. A stocking dyed in the piece will shrink slightly,and consequently the webbing is closer than if the yarn had been dyed before knitting. Dyed yarn being more expensive than white yarn, the waste resulting from goods damaged in the knitting is a more considerable item where colored yarn is used than where white yarn is employed, and,lastly, if the knitters stock can be carried in the white orders can be much more rapidly filled for special colors if they can be dyed in the piece than where the whole stocking has to be knit to order. By my method all of these difficulties are avoided. I knit the stocking of yarn in the ordinary way, using white or undyed yarn. proper point in the knitting of "the heel and toe I change the thread of the knitting, so that the tips of the heel and the toe areknit of a thread of mercerized cotton, alsowhite. The leg of the stocking maybe knit with a'rib and the foot attached thereto by the ordinary method of transferring. duced the knit stocking in the white, I have discovered a series of dyes by which the standard colors and contrasts for such stockings can be produced, by the use of. which I am able to dye such a bicolored stocking in a sin gle dyeing operation-that is, the dye both;

for the ground and for the contrasting color are placed in the same bath and bytheir se-. lective action dye the one the ground and the other the tips of differing colors. To do this,

it is necessary in each case to find a woolen dye which will not affect mercerized cotton:

and also a mercerizedcotton dye which will not aifect wool, and at the same time these dyes must be such that no chemical action takes place between them when mixed. The dyes by which I accomplish this resultwill now be disclosed.

Biackwithredtips,(forfifty-pounclgoods.) Wool-dye: Glauber salts, five pounds; sulfuric acid, three and one-half pounds; acidblack No. 54., two and one-half pounds. Tipdye: Chlorentine-red B, six ounces; tablesalt, two pounds. first in dye-bath at 90. Add sulfuric acid diluted in one-half gallon of water. Dissolve black No. 54 in boiling water and add to dyebath. Dissolve chlorentine-red B in boilingwater and add to dye-bath. Throw in tablesalt. Bring dye-bath to 140, enter goods, andbring to boil. Boil forty to fifty minutes until goods are up to shade.

Goods must be thoroughly washed and wrung out before dyeing. Use sufficient water in dye-bath to float the goods. .When goods are up to shade, lift and whizz. Wash off in ample bath of warm water, with one half pound of neutral soap and two ounces of acetic acid. Lift and whizz.

The process of handling goods given for black and red is the same for all black and color combinations but in every instance instead of dyeing with both colors at once it is equally feasible to dye the wool-dye first, as given above, lift and Whizz, then enter bath of chlorentine-red and table-salt, as above,

and boil fifteen minutes.

In every case above given the particular dyes selected are obtainable in the market under the designations given. In every case by As before, this maybe dyed wool-dye first and Enter at 140, bring thehuse of the above dyes at thecompletion of the dyeing process the heels and toes are dyed with the contrasting color with the same sharp definition as though the heels and toes had been originally knit with a threadof contrasting color. 7

It will be observed that this process results in a stocking not only having the contrasting color at the heel and too which for purposes of display is always'desirable in hosiery, but results in a stocking in which the parts subjected to the greatest wean-namely, the heel and toe pockets-are made of lnore'durable' material, a heel of mercerized cotton lasting twice as long as one knit of Woolen yarn.

Having thusdescribed my invention, I claim- 1. The process of making bicolored knit hosiery, which consists in knittingt-he leg and foot of undyed Woolen yarn and the tips of the heel and toe of undyed mercerized cotton; and then subjecting the'entire stocking to a dyeing process with a woolen dye of the ground color desired, which will be rejected by mercerized cotton, and with a mercerized-cotton dye of the contrasting color desired, which will be rejected by wool, substantially as described.

2. The process of making bicolored knit hosiery, which consists in knitting the leg and foot of undyed woolen'yarn and the tips of the heel and toe of undyed inercerized cotton; and then subjecting the entire stocking to a dyeing process with a woolen dye of the ground color desired, which will be rejected by inercerized cotton; and thereafter subjecting it to a second dyeing process with a mercerized-cotton dye of the contrasting-color desired, which will be rejected by wool, substantially as described.
